Soybean planting conditions, climate and geographical requirements

Introduction to soybean

Soybean is a plant of the Fabaceae family and the Glycine max genus. It is 30-90 cm tall. It is one of China's important food crops and has a 5,000-year cultivation history. It was called "shu" in ancient times. The main producing area is in Northeast China. It contains a lot of protein and is most commonly used to make various soy products. It can also be used to extract soybean oil and brew soy sauce.

Soybeans are commonly known as yellow beans. Soybeans can be divided into yellow beans, green beans, black beans, fodder beans and other soybeans.

Soybean Planting Conditions

Soybean is a thermophilic crop, but it also has strong cold resistance. It requires more water and is relatively resistant to waterlogging. During the growth period, sufficient water needs to be provided to maintain soil moisture.

Soybean Planting Climate and Temperature

The optimal temperature for soybean flowering and podding is 20-28℃. Podding is delayed at low temperatures, and it cannot bloom below 14℃. High-temperature plants end their growth prematurely, making it suitable for planting in temperate regions with high temperatures in summer.

Suitable areas for soybean cultivation

Soybeans are highly adaptable to the environment and have low requirements for soil. They can grow normally in most soils. However, if you want to improve the quality and yield of soybeans, you still need to choose soil with normal drainage and irrigation, rich humus, strong water and fertilizer retention capabilities, and deep and loose soil with a pH value of around 6.5-7. You can apply some base fertilizer to the soil to improve soil fertility.

The northern spring soybean zone should be divided into three sub-zones, the Huanghuai River basin summer soybean zone should be divided into two sub-zones, and the Yangtze River basin spring-summer soybean zone should be divided into two sub-zones.

Soybean planting time

Soybeans are suitable for sowing in summer and autumn. Summer soybeans can be sown after wheat is harvested if the soil is suitable. The best sowing time is June and no later than early July. Autumn sowing is generally done in August, with a sowing rate of 8-10 kg per mu.

Benefits of soybean cultivation

Experts say that in the next few decades the value range of soybeans will move up to between 800 and 1500 cents. They say that the history of soybeans being valued at $5 to $8 in the past few decades will become a thing of the past. So far, the three historical highs of soybean futures prices have been lower than the previous ones, and the number of times soybean futures prices have been in the high price zone has become less and less.
